This book investigates the historical mechanisms behind the shift in Welsh word order, specifically focusing on the loss of the verb-second (V2) constraint over the last millennium. David W. E. Willis, a scholar of Celtic linguistics, utilizes a comparative framework to analyze the evolution of Welsh syntax. By examining the interplay between literary records and spoken language, he argues that these syntactic shifts are not isolated anomalies but are instead reflective of broader typological patterns found in European languages.

Linguists and Celtic scholars recognize this work as a rigorous contribution to the study of syntactic evolution. Experts frequently highlight the text for its technical precision and its ability to bridge the gap between specific Welsh historical data and general linguistic theory.
